Abstract

PURPOSE:To restart the working that is performed before the generation of service interruption when power supply is restarted by deciding whether the discontinuation of power supply is due to the break of a switch or service interruption and therefore saves the contents of a register which stores the relevant data in a service interruption mode while the DC voltage of a device is kept at a workable power supply voltage level. CONSTITUTION:When the voltage of a DC power supply reaches an intermedium level M before a switch OFF signal is supplied from a power supply unit 11, service interruption is decided and an interruption flag equal to 1 is set to a bubble memory 14 through a control part 15. Then the data required for a working program of a device to be controlled which is stored in a data register 16 is stored to the memory 14 via the part 15 and then saved. When the power supply is restarted, it is decided whether the stored service interruption flag is ''1'' or not. If the flag is not ''1'', it is judged that the service interruption is due to the break of a power supply switch. Thus the power supply is turned on again. If the service interruption flag is ''1'', it is judged whether thesevice interruption processing end flag that is stored next is ''1'' or not. If the end flag is not ''1'', an alarm is given to the operator. If the end flag is ''1'', it is judged that the device can be energized. Then the working step is reset.

Structure of the Invention In the present invention, data blocks instructing work steps are stored in a non-volatile memory, and even if a power outage occurs during an operation, the interrupted operation is resumed without returning to the starting point when power transmission is resumed. In a power outage processing method for a device using the continuous absolute position feedback method, a switch-off signal is obtained when the power switch of the AC power supply supplied to the device is cut off, and a signal obtained by converting the AC power supply is obtained. An intermediate value between the specified voltage value of the DC power source that operates the device and the low voltage limit value that allows the device to operate is determined, and when there is no switch-off signal and the voltage of the DC power source reaches the intermediate value. In the event of a descent, the non-volatile memory is used to set the power outage flag to "1", store related data, and save the contents of Zosta, and the setting and save are performed by the DC power source. When the voltage reaches the low voltage limit value, the power failure processing completion flag for the nonvolatile memory is set to "1", and when the power is turned on again, the power failure flag of the nonvolatile memory is set to "1". If the power outage flag is "1" and the power outage processing completion flag is "1", the device continues the operation as before the power outage, and if the power outage flag is "1", the power supply sequence is performed. There is provided a power outage processing method for a device using an absolute position feedback method, characterized in that an alarm is issued if a power outage processing end flag is not "1".
